Vitamins

Vitamins are organic compounds that are essential for the normal functioning of the body. They are required in small amounts and cannot be synthesized by the body, so they must be obtained from the diet. There are 13 essential vitamins that the body needs to function properly, and they are classified into two groups: fat-soluble vitamins (A, D, E, and K) and water-soluble vitamins (B-complex vitamins and vitamin C).

Fat-Soluble Vitamins

Vitamin A: Essential for vision, immune function, and reproduction.
Vitamin D: Important for bone health and immune function.
Vitamin E: Acts as an antioxidant and helps protect cells from damage.
Vitamin K: Necessary for blood clotting and bone health.

Water-Soluble Vitamins

Vitamin B1 (Thiamine): Helps the body convert food into energy.
Vitamin B2 (Riboflavin): Important for growth, red blood cell production, and energy metabolism.
Vitamin B3 (Niacin): Supports proper digestion, healthy skin, and nerve function.
Vitamin B6: Helps the body make neurotransmitters and hemoglobin.
Vitamin B12: Essential for red blood cell formation and neurological function.
Folate (Folic Acid): Important for cell division and DNA synthesis.
Vitamin C: Acts as an antioxidant and is necessary for collagen production, wound healing, and immune function.

Sources of Vitamins

Vitamins can be found in a variety of foods, including fruits, vegetables, dairy products, lean meats, and whole grains. It's important to eat a balanced diet that includes a variety of nutrient-rich foods to ensure an adequate intake of vitamins.
